Key Details

• Transaction date: 2026-03-16; Form 4 filed 2026-03-17 (timely filing).
• Type: Grant / Award (derivative) — 500,000 RSUs at $0.00 per unit.
• Vesting: The RSUs vest in 12 equal quarterly installments beginning June 8, 2026, contingent on continued service; RSUs have no expiration date. (Footnotes F1 & F2)
• Shares owned after transaction: Not specified in this filing.
• Filing timeliness: Report appears timely (filed next day).

Context
RSUs are a common form of executive compensation: each unit represents a contingent right to receive one share upon vesting, so this award does not involve an immediate cash payment or open‑market activity. Such grants are primarily compensation-related and should not be interpreted alone as a direct market signal; outright purchases by insiders tend to be more indicative of personal buying conviction.
